incarceration. are there certainly people who we actually think would be better off in prison than not being in prison? those types of decisions, i think, are going to be much more useful coming out of the neuroscience in the near term. in the long term, maybe we can get to the point where we make individualized decision-making, but so far it hasn't actually panned out. >> to all of you, do you think that it would be appropriate to keep this out of the courtroom, for instance, until there is a lot more certainty, or should we be using it now and run the risk that we're reaching potentially wrong conclusions? >> i'll jump in first on that and say it's already here. so the idea that we should wait for the science to get better, i think, is just, it's too late for that. so the cat is already out of the bag. the question is what do you do now that it's in the courtroom. well, we have dualing experts. we have judges sitting in a gate keeping role who have to decide whether or not the evidence should be admissible and whether it should be permitted in a case.
